Heterogeneity stabilizes reciprocal altruism interactions.

Journal of theoretical biology - 7 Mar 2001

Fishman M A, Lotem A, Stone L

Abstract excerpt

In considering the phenomena of reciprocal altruism few would dispute that there are differences in individual quality-in particular, that for some individuals, at least on occasion, the cost of doing favors will exceed the potential of future benefits. That is, at any given time, a typical population is heterogeneous with respect to the affordability of reciprocal altruism. However, methodological limitations of...
